12volt a Viair constant duty----for 110 volts there are a million that will work---the term "best" is subjective, How much room, is weight a factor, noise etc; You should get a lot of suggestions here so just read and think it over.
I installed a 12v Viair system with a tank (pricey, very handy)----for reasons other than airing tires----and I threw in a nasty air horn on a gas rig for the heck of it----sweet.
I can't really reccomend it because of the price---but you could look at their website and decide for yourself. It suits me fine and it is a quality set up.
